Beware of Z77X UD5H

So you are saying because you have an issue with your RAM not working at settings you would like then all the boards must be faulty? really?

As stated in that reply to you there is no SPD setting or even recommended voltage to use when overcloking the RAM over 1600Mhz which is all Samsung have qualified the RAM to (hence why its sold as 1600Mhz RAM and not sold or rated higher)


If you wanted to run your RAM at the speeds you are wanting without issues then you buy RAM rated for and tested to those settings, overclocking and the amount you can achieve by overclocking vary greatly per component, nothing is guaranteed.

Just because you may have seen the same RAM achieve those speeds above 2000Mhz and at low volts doesn't mean you will get the same results, usually when you push something above and beyond its rated operating specs you can expect to need to increase the operating voltage.

As mentioned above, try the BIOSes available at tweaktown.

There's lots of people using this motherboard and RAM here on these forums without this issue.

Does that not show you that you might either have a faulty motherboard or ram and should RMA one of them? Try later BIOSes?

Coventant - Im thinking of putting together a pc with almost exactly the same components.

How do you rate it? Compared to the PC in my sig, it will be a big step up right?
 
Stulid: It seem my samsung will not stable at 2133MHz at 1.45v @ 10-10-10-28-1T as the board kept reset to 1.50v itself and overclock become unstable.

So, I can understand OCUK did say the samsung might not guarantee to run 2133MHz on most board. So, I revert back to stock setting and left all on auto but change the memory voltage to 1.35v at 1600MHz @ 11-11-11-28-1T and hope the board didn't reset itself back to 1.50v. I had updated bios version to F8 now and see what happen.

The board are great as I can get 4.6GHz easy on auto but can't get stable with memory above 1600MHz but I suppose so, it Samsung Green memory that come with 1600MHz at low voltage 1.35v and will stick to it.

Also I see you are trying to run the timings at slightly tighter settings than its been tested for at 1600Mhz.


Instead of decreasing the timings, try slackening them off as the speed goes higher.


Edit.. also you don't think your thread title and opening sentence of your first post is a little presumptuous?

Heh, I upgraded from an E6750 and it's light years ahead of that :D but from a Q I'd say still worth the upgrade yes.

My view is if you have an overclocked 920 or above wait for Haswell and decide, below that it's well worth the upgrade now

Instead of trying to jump right in at 2133, why not do what overclockers generally do and work your way up? ;)

Try 1.45v and 1866, if that works try 2000, test as you go and make small jumps. It will make it far easier and you'll find the best volts-speed tradeoff for your RAM
 
Right, my board is now no reset at all after updated bios F8 with 2133MHz and 1.45v and it no problem now from cold boot.

covenantuk - I did 1600, 1866, 2000 and then 2133MHz all seem running ok now with F8 bios version.

So, do you want to change your opinion from don't buy this board as RAM doesn't work....to I have updated my BIOS and everything is working fine now?
 
I've just bought this Mobo and got worried when i read the title, if i'm honest i didn't understand most of what was being said, but its good to hear the gigabyte rep on these forums being helpful when needed, dont see this often
 
Just goto say what a troll thread due inexperience !!! :rolleyes:

This board and chipset are brand new and all new motherboards have teething problems at 1st, hence new bios updates everyother week. Plus the fact you were trying to burn the ram at max from get go, take your time do it slowly.

This is the best motherboard I have ever had, no droops at all when set right, I could goto 5ghz+ but no point am happy at 4.8! :p

I think you will find you have made a very good purchase and once you get experienced with the board you will love it! :D
